Half Thread 4.8 Grade Steel Hex Bolt Hex Head BoltDin 933 For Architecture
Products Description:
Six angle bolt, six angle head bolt (part screw) -C and six angle head bolt (full thread) -C. Also known as the six hexagon head bolts (coarse hair) six hexagon head bolts, iron screws.
Six angle bolt: a fastener consisting of two parts, the head and the screw (the cylinder with external thread). It needs to cooperate with the nut to fasten and connect two parts with through holes.
This form of connection is called a bolt connection. If the nut is swirled down from the bolt, the two parts can be separated, so the bolt connection is a detachable connection.
According to the shape of the head six head, round, square head, countersunk head, and so on in connection to the smooth surface without protruding place head heavy, because the countersunk head can be screwed onto the parts. Also can be screwed into the round parts. With the tightening force can be bigger, but the large size six. The head is the most commonly used angle
Advantage:
The advantage of acid tin plating is that the plating speed is faster. And the coating is bright and meticulous, deep plating ability. The plating solution has a strong tolerance to impurities, and the operation at room temperature is more energy saving. However, the plating method also has shortcomings, that is, the dispersing ability of the bath is poor, the porosity of the coating is higher, the brazing is not as good as the alkaline tin plating, and the two valence tin is hydrolyzed. Therefore, the six angle head bolt acid tin plating is divided into sulphate tin plating, fluorborate tin plating and oxide tin plating because of different conductive medium. At present, some special industrial six - corner head bolts are used in this tin plating process.
